- preperation (concensus to change)
- process think (which process why)
-creation (identify processes)
-technical design (reengineering) - social design (people)
- implementation ( take away resistance)
what do all BPR methodologies focus on?
analyzing and improving existing processes
what is an activity diagram?
another word for the business process reengeneering
what is system design?
BPR use in the context of IT. so people thinking about how to use IT in order to optimize the business processes
how is system design done?
- analyzing and improving a process
- analyzing the role of information in that process

- identifies key flows of information
- seeing the information that flows through different units
what is information flow modeling for?
to determine whether:
- units receive necassary information
- the information is correct in terms of accuracy, speed, cost, sufficiency
- the improvements that can be made through IT or other ways
